4/VI, 11/2 o'clock, evening

Comrade Botin! When you were with me today, I had only 2 minutes, as I was called away from an important meeting.

Now I have a free quarter hour and therefore can (and must) tell you in more detail and more clearly that manifest errors have clearly been made and that we must directly, honestly, decisively renounce these errors. Otherwise a most serious matter will be spoiled.

The error was, firstly, that there was distrust toward the "specialist,"232 which prevented him from being told everything straight away and prevented the experiment from being set up quickly; secondly, that the "black," preparatory work was being done by you personally, diverting you from your actual work, whereas the entire mass of "black," that is, preparatory, work must be transferred to mechanics, assemblers, electrical technicians, etc., of whom we will find a dozen. And in order to separate your actual work from preparatory or auxiliary work, we need constant consultation with the "specialist."
